2/14/2014 Case 1: Question 5 Case 1: Diagnosis After 5 days of IV solumedrol the patient experienced • Initiated empiric solumedrol 1g IV x5 days minimal improvement. The preferred next step in management is? • CSF: 1. Prednisone taper and IVIG – No oligoclonal bands 67% 2. Prednisone taper and immunosuppression – IgG index: 0.77 (0.23-0.64) (Rituximab) • SSA (Ro) Ab: 156 (0-40 AU/mL) 3. Prednisone taper and immunomodulators (interferon) • SSB (La) Ab: 0 (0-40 AU/mL) 23% 4. Another course of IV solumedrol • NMO ab: >160 U/mL (<4) 7% 2% 2% 5.

2/14/2014 Case 2 Case 2 • History • PMH – 33 yo man presents with psychosis and suicidal – Suicide attempt in 9/12 – 1.5 years of paranoid delusions following the end ideation – 1 week prior to admission had intermittent LE of a serious relationship – History of polysubstance abuse (marijuana, paresthesias and numbness – 2-3 days prior to admission the LE symptoms ecstasy and methamphetamine) with rare etoh worsened and he was unable to walk use • Meds • Review of Systems – Noncompliant with risperidone and lorazepam – Recent weight loss but unclear how much – Otherwise unremarkable ROS Case 2: Exam Case 2: Imaging • MS: oriented, normal digit span, 0/3 recall • CN: unremarkable • Motor: normal bulk and tone. 5/5 throughout except 4+/5 in left triceps, interossei and hamstrings • Reflexes: 1+ in the UEs, 3 knees, 2+ ankles, toes down going • Sens: decreased to vibration and proprioception throughout (legs> arms). Pinprick and temperature intact • Coord: dysmetria in all 4 extremities with truncal ataxia • Gait: unable to stand without assistance Sag T2 Axial FLAIR 5

2/14/2014 Case 2: Question 1 Case 2: SG What do you think will be most useful in guiding • More history the differential diagnosis? – Patient admitted to using 1. Serum labs 90% whippets twice daily for a 2. Lumbar puncture year and recently had been 3. More of a history regarding attempting to overdose substance abuse – “thousands of cartridges” 4.

Vit B12 • Vit B12: 294 (236-888 pg/dL) 2. Homocysteine – was 618 on 9/19/12 3. Methylmalonic acid 24% • Homocysteine: 197 (<10 umol/L) 4. Peripheral smear 16% • Methylmalonic Acid: 3.85 (0-0.4) 5.

Daily oral B12 supplementation 3. Daily high dose IM B12 supplementation 6% 4% . . . . . . . . r . 2 s a 1 o c B d e h a l v g i r t o h i r o y y p i l l p a i a u D D S Case 2: Repeat imaging Case 2: Question 4 Would you perform an LP at this time 70% 1.

2/14/2014 Case 2: follow up Case 2: Pearls • N 2 0 is an increasingly common drug of abuse • CSF – 1 RBC, 0 WBC, gluc 60 mg/dL, prot 78 mg/dL and is readily available • N 2 O causes the oxidation of Co + to Co ++ , – CSF gram stain and culture negative thereby inactivating B12 in vivo – Oligoclonal bands not detected • B12 is necessary for the synthesis of – IgG index 0.52 methionine which is needed for myelin sheath • Continued with high dose B12 protein supplementation. Patient has not returned • B12 levels may be normal but the patient is for follow up yet functionally B12 deficient Thank You • Questions? 8
